Harrison Ford & Sean Young in “Blade Runner”, 1982
Blade Runner - The sixth replicant. In the movie Bryant mentions a sixth replicant. An early version of the script called for a character called "Mary" (Stacy Nelkin was even cast in the role). The character's scenes were dropped due to budget constraints, but one reference to the extra replicant had already been recorded and survived the changes, creating a small continuity error in the process.
